Flame retardant wallpaper paper manufacturing method

The present invention is to prepare a flame-retardant wallpaper paper prepared by separately applying a paint mixed with inorganic pigments, flame retardants, adhesives in order to give a more excellent flame retardancy and printability after surface treatment using a water-soluble flame retardant in the paper press of the papermaking process It is about a method.

Conventional flame retardant paper manufacturing methods are largely classified into two types: physical treatment such as impregnating, impregnating, and applying the flame retardant, and chemical reaction such as esterification, etherification, copolymerization, and crosslinking using reactive-OH groups. Mainly, the physical method was adopted. First, the method of internalization is required to add a large amount of expensive flame retardant to impart the desired flame retardancy due to low residual ratio when water-soluble flame retardant is added to the puff slurry or when a flame retardant inorganic material is used as a filler. Secondly, the impregnation method is not only complicated but also complicated in size, such as impregnating flame retardant to the inside of the raw material, and making a separate facility for impregnation. (SIZE 度: The effect of preventing ink from spreading) is very poor, Third, the method of coating is difficult to impart sufficient flame retardancy when the flame retardant is applied to the original paper having a high degree of sizing, so that it is difficult to impart sufficient flame retardancy, and is not suitable for obtaining wallpaper paper having excellent printability. In applying the flame retardant in the press, in order to give sufficient flame retardancy only by the size press treatment, it is necessary to lower the speed of the paper machine, which leads to a problem of lowering the productivity and to the addition of the water-soluble flame retardant to the mineral paint because the fluidity of the mineral paint used in the applicator is very difficult. If the viscosity is increased or agglomeration occurs and the coating cannot be applied to the paint, a method of imparting flame retardancy by mixing and applying a flame retardant to the mineral paint has not been developed.

In order to solve the problems of the related art, the present invention provides a flame retardant by mixing a water-soluble flame retardant with a sizing liquid composition in a sizing press of a papermaking process, and at the same time obtains a required sizing degree, In the braid spreader, a certain amount of paint mixed with a flame retardant is applied to an inorganic pigment to have a flame retardant residual ratio of 100%, excellent flame retardancy, and to manufacture a wallpaper having excellent size and printability.

Hereinafter, the content of the present invention will be described in detail.

At 100 mv, it has a very fluid composition, but when water-soluble flame retardant is added to the composition, stable inorganic pigment particles work with hydrophilic flame retardant, resulting in zeta potential.

Since it became 4mv and the fluidity worsened, the flame retardant treatment was impossible in the coating process as described above. By adding a surfactant to the water-soluble flame retardant to inactivate the electrochemical properties of the flame retardant itself, the above-mentioned problem is solved by dispersing the mineral pigment.

Prior to applying this invention to the process of manufacturing raw paper in a general paper mill, the results of testing in the laboratory to measure the effect of the invention are as follows.

Experimental Example

Base paper: 90g / ㎡ (not sized liquid)

Flame retardant: Guanidine sulfamic acid, Guanidine phosphate, Ammonium monophosphate, Ammonium sulfamate, Amide sulfonic acid salt.

Using the size liquid composition and the base paper, 300% of the water-soluble flame retardant was added to the starch in the sized liquid composition to apply the water-soluble flame retardant to 5-10% by weight of the base paper, and then the base paper was used to solidify the water-soluble flame retardant. After adding 10% of surfactant to 40% of aqueous solution, apply 30% to pigment of coating liquid composition and apply water-soluble flame retardant to 5-10% of original weight so that the total amount of flame retardant is 15% of original weight After application, the size, flame retardancy, and printability were tested.

Application Method: Bar Coating

Flame retardant: Complies with KSM 7074

Size: According to KSM 7025.

Printability: Print sharpness and ink repair are shown by 5 point method.

Therefore, it was found that by applying some flame retardant in the size press and reapplying a certain amount of the flame retardant in the air knife or braid spreader, a flame retardant wallpaper having excellent flame retardancy, size and printability can be manufactured.
